On the whole, this lift motor 124 that operates in of this lift mechanism operationally takes place when meshing with this spinner member 140, so that this spinner member 140 rotates to an off-position, i.e. one " cam is last " or " central authorities top " position, at this place, the Central Line of this second deflection element 154 rises to this central authorities tops (that is these these central longitudinal axis 129 tops of 128) of 128.At that point, this second deflection element 154 makes this spinner member 140 also therefore it can be operated meshing and recommend bar 50 with this and carry out operating meshing with these lift motor 124 end with this bolt 130 suddenly.Particularly, this activates this actuating arm 56 of bolt 148 contacts.Whereby, this second deflection element 154 provides through this spinner member 140 and makes this recommend the strength that bar 50 moves into these extended positions 64.On this extended position, this is recommended bar 50 meshing these stayed surfaces 12 and this toy car 10 and recommends one and lifted from this stayed surface 12 in the action.This spinner member 140 continues rotation (being docile and obedient clockwise in Fig. 6 to 8) and finishes meshingly to recommend bar 50 with this, and this is recommended bar 50 and is retracted this retracted position 62 again by this first deflection element 60.The control of this lift mechanism and operation be described in detail as follows literary composition.

Fig. 6 to 8 describes the various work angles position of this spinner member 140." loosening " position 156 (being approximately 3 o ' clock positions that this spring brake 146 is represented with solid line) that Fig. 6 illustration one is initial, wherein this second deflection element/spring 154 is positioned at its minimum extended position, and one " parking " position 157 (being approximately this spring brake 146 4 o ' clock positions that are represented by dotted lines), wherein this second deflection element/spring 154 omits toward the clockwise direction and " loosens " position 156 from this and extend relatively.One of this spinner member of Fig. 7 illustration " preload " or " pre-release " position 158 (being approximately this spring brake 146 8 o ' clock positions that are represented by dotted lines), and one " release " position 159 (being approximately 9 o ' clock positions that this spring brake 146 is represented with solid line).This of this spinner member 140 of Fig. 8 illustration recommended the actuated position 160 (be approximately this spring brake 14611 o ' clock positions) of bar 50.This control circuit 174, this controller 175 preferably, can decide these position of rotation of this spinner member through the state of the preload of preferably opening under normal operation and

park switch

188 and 190, these switches change its state (promptly cutting out) through the mode with this first and second cam face 150 and 152 interactions.At length say, when this spinner member 140 when the clockwise direction shown in Fig. 6 and 7 rotates, this preload switch 188 by with this first cam face 150 start from approximately this brake 146 2 with 3 o ' clock positions between and terminate in contacting between 7 to 8 o ' clock positions of about this brake 146 and be closed.This park switch 190 is closed by starting between 4 o ' clock positions of approximately this brake 146 with this second cam face 152 and terminating in contacting between 11 o ' clock positions of about this brake 146.Therefore, when this stand 157 is rotated toward the clockwise direction at this spinner member 140, after this preload switch 188 is closed, by the expression of closing of this park switch 190.This preload position 158 is disappeared by the ensuing signal of this preload switch 188 on about 8 o ' clock positions and represents.The signal of this park switch 190 on about 11 o ' clock positions disappear the meshing and arrangement of this spinner member 140 of expression this recommend bar 50.This controller 174 these switches 188 of monitoring and 190 state to be operating this lift motor 124, with recommend one/make this lift motor 124 after the jump action and this spinner member 140 is meshing again and make this spinner member 140 rotate to required angle position to be engaged in the next operation of this lift mechanism.

The operation of this lift mechanism and control as follows.Continuation is with reference to Fig. 6 and 7, and when this toy car 10 was closed, this spinner member 140 was preferably located on this stand 157.This on/off switch 182 is used to open the state that this toy car 10 and this control circuit 174 begin to monitor this weight switch 184 and this action perceptron 185.When this control circuit 174 realizes that this toy car 10 is in the normal operating condition of recommending action or state (be weight switch load/close and the minimum predetermined wheel velocity is reached), this control circuit 174 can start this lift motor 124 so that this spinner member 140 rotates into this " preload " position 158 (dotted line of Fig. 7) toward the clockwise direction, and wherein this spring 154 extends near its maximum but still this first brake area 162 is secured on this bolt 130.This spinner member 140 is moved into this preload position 158 automatically and is recommended the required time of instruction to reduce inferior one of this lift mechanism reaction user startup.When this element 140 from this stand 157 (toward the clockwise direction) when changing this preload position 158 over to, this preload switch 188 loses itself and the contacting and unlatching of this second cam face 152, illustrates this control circuit 174 to stop the operation of this lift motor 124.

The jump switch (not shown) that the user sees through on this wireless launcher 210 of operation begins the action of this act bar 50.This wireless launcher 210 transmits a unique discontinuous signal with the beginning skip functionality.When this skip functionality is enabled, other function (as, the operation of this linear motor drive 110 is the operation of this driving motor 92 maybe) can be overlooked as invalid.If these spinner member 140 former being positioned on this preload position 158, then the operation of this lift motor 124 can be performed.If this spinner member 140 does not begin to move from this stand 157 as yet, then this recommend/skip instruction is transmitted Shi Buhui any action takes place.

With reference now to Fig. 7,, recommend instruction if this toy car 10 is received when this spinner member 140 is positioned on this preload position 158, then this control circuit 174 can start this lift motor 124 so that this spinner member 140 rotates into this actuating or release or cam in last or central top position 159 (solid line) from this preload position 158 (dotted line) toward the clockwise direction.This off-position 159 roughly is positioned at the clockwise direction (9 o'clock of this brake 146 or shortly past the position at 9 o'clock) of this preload position 158, wherein the vector of this spring 154 (connecting this top bottom-disc spring brake 34) to this spinner member spring brake 146 from these central longitudinal axis 129 belows of this output shaft 128 move to this central longitudinal axis 129 directly over.(and being subjected to this lift motor 124 to secure to these bolt 130 resistances of this first brake area 162) becomes clockwise direction to the torsion of this spinner member 140 due to this spring 154 from counterclockwise.When a clockwise torque was applied on this position 159, this spinner member 140 can rotate freely with respect to these output shaft 128 ground.When this spinner member 140 shifted out this off-position 159, this spinner member 140 can be suddenly pullled toward the clockwise direction to finish it with this bolt 130 and this motor 124 can be operated meshing (seeing through separating of this brake area 162 and this bolt 130) and return this and loosen and stand 156 and 157.Therefore the action of this bolt 130 in this first and

second brake area

162 and 164 slits that defined is used to make this spinner member 140 and this lift motor 124 to finish meshing.

With reference now to Fig. 8,, one to jerk at this, these actuating bolt 148 meshing these are recommended bar and are activated arm 56, make this recommend bar 50 and change this extended position 64 over to from this retracted position 62.When so operating, this first end 52 freely of recommending bar knocks this stayed surface 12, recommends one and advances this toy car 10 in the action.When this spinner member 140 continues to turn to this to loosen and when stand 156 and 157, this actuating bolt 148 can be recommended bar with this and be activated arm 56 and finish meshing and this first deflection element 60 can make this recommend bar 50 to return this retracted position 62.

The distribution of weight of this toy car 10 and this are recommended the intensity and the direction of the strength that bar 50 produced and can be adjusted, so that the final strength that acts in recommending action on this toy car 10 makes this toy car 10 not only from these stayed surface 12 vertical lifts, can also throw to front end ground through at least one complete light throwing of 360 degree rear end and overturn forward.Therefore this toy car 10 can be carried out recommending and rotary movement of a combination.

After this spinner member 140 is released, this control circuit continues this lift motor 124 of operation with rotation toward the clockwise direction, up to this bolt 130 in this release position 156 or near it till meshing again this first brake area 162, and preferably continue rotation, till it moves into this stand 157 with this spinner member 140.If (minimum speed of the weight on this weight switch and this near front wheel 70a) appears in predetermined operations state once more, this control circuit 174 will make this spinner member 140 return this pre-off-position 158 and recommend action to carry out another.

If this toy car 10 is kept static one section Preset Time (as 2 minutes), this control circuit 174 can be configured to and impels this lift motor 124 to rotate (promptly towards the counter clockwise direction shown in Fig. 6 to 8) backward so that this spinner member 140 goes back to this stand 157.Mass loading/the wheel velocity of action is pre-conditioned is satisfied once more if this toy car 10 is driven once more and recommends, and then this spinner member 140 can go back to this preload position 158.Similarly, when this toy car 10 was closed through this on/off switch 182, this spinner member 140 preferably returned this stand 157.Under these two kinds of situations, this operation can be shortened the duration of the mechanical stress that produces because this spring 154 is under the tension force on the part of this toy car 10.Preferably, when this toy car 10 was closed, this stand 157 was returned in the interaction that this spinner member 140 sees through this on/off switch and this park switch 182 and 190.This is that the one second bar 182a that sees through this on/off switch 182 finishes this park switch 190 and the mode of the reverse drive circuit polyphone wiring of these power resources 200 and this lift motor 124.When this on/off switch 182 was moved to open position, this bar 182a saw through this reverse drive circuit of this lift motor 124, comprises this park switch 190, makes supply of electric power be connected to ground.When motor backward (towards counterclockwise) when turning over this stand 157, this park switch 190 is opened, and interrupts this circuit and stops this motor 124.Because this preload and park switch are indicated the various angle positions of this spinner member 140, this microprocessor 175 can enroll program to carry out other functions, to comprise the initial position of reseting this spinner member and to diagnose the choking phenomenon of this output shaft 128.

From above, we are appreciated that the toy vehicle design that the present invention includes a novelty, and it has a novel lift mechanism that can produce the outstanding feature of recommending action and safety, to avoid the risky operation of this lift mechanism.

One of ordinary skill in the art will appreciate that the variation of the foregoing description all is feasible not deviating under the invention theory of its broad sense.As, though embodiment starts this lift mechanism to start a remote control signal, the Starting mode of other kenels also can be used.For instance, this lift mechanism can drive this toy car after a period of time towards a direction of advance, or when by the time a specific speed arrives, or after this toy car has driven one section Preset Time towards either direction by the time, or be just to start after receiving the instruction of carrying out a specific action.Though the present invention this with the four-wheel pattern as preferred embodiment, the present invention also can comprise having three-wheel or more than the toy car of four-wheel.This toy car 10 is preferably controlled with radio (wireless) signal of this wireless launcher 210.Yet the controller of other types also can use, and comprises the wireless controller (as infrared ray, supersonic speed and/or sound actuation control device) of other types, or even cable controller etc. all can.This toy car 10 for example plastic cement or any other suitable material such as metal or synthetic material is made.In addition, the size of this toy car 10 can change, and for example, the part of this toy car can be made littler or big than other parts.Therefore should be appreciated that the present invention is not limited to the specific embodiment that disclosed, it should comprise the spirit that is covered by the claim scope of enclosing and all modifications in the category on the contrary.
